Cometic Oldsmobile Gen-2 Rocket V8 .075in MLS Cylinder Head Gasket - 4.270in Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) cylinder head gasket is a prime example. It’s designed for Oldsmobile Gen-2 Rocket V8 engines, specifically for builds that push the limits and need reliable sealing. This gasket has a 4.270-inch bore and a compressed thickness of .075 inches, making it suitable for high-output applications where a precise seal is critical.

What makes these MLS gaskets stand out is their construction. They're built from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well with different engine block and head materials, including aluminum to aluminum or aluminum to cast iron. This means you don't need extra sealants; the gasket itself is designed to provide maximum sealing performance right out of the box. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements, like the .075-inch thickness on this particular gasket.

This gasket fits a wide range of vehicles from the mid-70s to early 80s, including models like the Buick Century, Chevrolet Camaro, and Oldsmobile Cutlass Supreme. It's a solid option when you're rebuilding the top end of your engine and need a dependable seal that can handle the demands of a performance V8.
